those who always give charity are resented?

I read on the internet that people in trouble or trapped hate the lack of charity of those who reach out to them more than those who don't even see them.

One person responded to this by saying If you put your hand out to take a wounded stray cat to the hospital, you are sure to be bitten, and you will not be thanked, and it's arrogant to say - I'm helping him.

I think this is an interesting way for the mind to work. I never imagined that doing a good deed would make me feel bad in the least before, but now I understand.
